because they want to have a new pope in place for holy week, which begins with palm sunday on the 24th, but, also, of course, because they don't want to project an image of being disunified and paralysis and gridlock and chaos to the world. so, i think all the cardinals feel some degree of pressure to get this done. on the other hand, none of them can actually control how long this is going to take because there is no shot clock in a papal election. the way this works, they have to keep going, keep balloting until someone passes that magic two-thirds threshold, which in this case, would be 7 7 votes to become pope shortest one took two hours and the longest was almost three years. the truth of it is, as much as they might like to speed this along, ultimately no one, including the cardinals, knows exactly how long it will take. >> no shot clock in a papal election, although that would be very interesting, i have to say. john allen in rome, thank you for that.
